The Chimney Fire in San Luis Obispo County grew by 4,000 acres overnight and is now at 37,000 acres. The wildfire is approaching the historic landmark Hearst Castle where newspaper magnate William Randolph Hearst once lived. The wildfire also threatens a Monterey County community.

The Chimney Fire was threatening the community of Bryson Hesperia, which extends into both counties, Chimney Fire spokesman Bud Englund said.

The entire community has been evacuated because of the threat from the fire, but the fire has not reached Monterey County, he said.
